I am currently working with the STM32U5G9J-DK1 development kit interfacing with a Tianma-based display. I have successfully managed to update the display using adaptive command mode with DSI long and short write commands. However, I am encountering i...
Hi I use STM32H743XI and W25Q256 for my design.And I notice W25Q256 has two speed 133Mhz(W25Q256JV) and 104Mhz(W25Q256FV), currently I use W25Q256FV, since I only use this flash with memory map mode, is it necessary to replace with W25Q256JV? Will th...
Hi,My customer wants to design a high speed ADC aquisition system with minimum 100 MSPS rate and 14-bit resolution.The external ADC devices like AD9258 and AD9268 have this capability, which we are proposing.Would it be possible to use a high speed S...
Hi,we would like to add live video playing/streaming to an STM32-based board we are designing that uses MIPI-DSI to drive a touch display, and we are at the stage of choosing the micro.Ideally it would stream from HDMI signal but we can use another i...
I'm working on a custom board with a STM32H723ZG. I'm also using external sd ram part IS42S16400J-6TL found here (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS42S16400J-6TL/2708625). I've followed the excellent s...
Hi,I am using STM32H725REV6 chip in our product. Based on my understanding, since this is 68pin version which doesn't have VREF+ pin, the VREF+ is internally connected to VDDA. If my understanding is correct, I would like to ask if we would like to u...
We're bringing up yet another custom board with the STM32H735 as the core processor. Built the first one, handed it to the software guy, and a few minutes later he says it's broken. Won't program, won't go to DFU mode, nothing. "You must have zapped ...
HiI have implemented ADC1 on a DMA and verified its operation. I then implemented the ethernet stack and verified that it can be pinged. The issue I'm having is that the ADC DMA stops working once the ethernet stack is implemented. I believe the erro...
I have three variables:volatile uint16_t a[20000];volatile uint16_t b[20000];volatile uint16_t c[20000]; However, I only have one DMA channel.Can I use the DMA to transfer these three variables together in circular mode?starting with the first 10,00...
Hi I am using a STM32L433 and have a digital input pin, which is checked on bootup and enables the USB if 3.3v is in the pin. When working in debug mode, it always works, but when I switch to release mode , using stm32CubeIDE , it always reads 0v,...
